There was never enough for everybody. So second best option is, known infected + healthcare. Health professionals work under heavy viral load, which is positively correlated with your chance of getting sick and having a bad outcome. Which means in an overloaded healthcare system without adequate amounts of PPE (like Italy now), doctors will be dying, even if they were young and otherwise healthy. And dying doctors drops the system capacity too.
(Capacity of most healthcare systems seems to be limited by the amount of beds and ventilators available, but these you can always make - and China is indeed making them full-steam, to help the rest of the world. You can't make new doctors that quickly, and there isn't much of them either.)
Those are basic precautions that depend only on the availability of soap. Face masks need to be worn properly to work, and in cultures where people don't wear them normally this is an issue. Only medical staff really has a valid use for face masks now, also because of limited availability.
But clearly this is not insurmountable.
They aren't very effective and people who use them tend to touch their face a lot more. Not a good idea - unless you are infected.
If you are an expert in anything watching this play out everyday has become a gigantic nuisance and a distraction. Not because it matters what the herd is debating but because of the effect it has on leaders, decision makers etc. It piles pressure on them to waste time/resources/energy reacting to the herd.
Even with the info explosion the educated herd is as dumb as it has ever been, probably dumber, for the simple fact there is always more info than whatever you hear on the news or can read up in 2 weeks.
As if the educated herd made a diff to the election of Trump or Brexit. Some people argue the response is evolving with each crisis. I haven't seen any evidence of that.
This has been my standard reply to the "It's just a flu" concept for some time now.
Aside from all this, it's incredible how difficult it is for people to think about this using all the info available (long onset of symptoms, asymptomatic spread, high % of hospitalizations / intensive care, etc) plus thinking in the long term.
I know the generalized idea is no face masks if you don't have symptoms, but if we all used them it might have a good effect on curving the spread.
Unfortunately, western cultures associate face mask with sickness, and are frowned upon.
